Eveready 30W R39 Reflector Bulb E14 Warm White 2700K – Lava Lamp Special Purpose

Description

The Eveready R39 is a 30W incandescent reflector bulb with an E14 (small Edison screw) base, rated at 180 lumens and 2700K warm white. This is a special-purpose bulb designed specifically for lava lamps and certain decorative light fixtures that require both the heat output and the reflector shape of a traditional incandescent bulb. The R39 designation refers to the 39mm reflector diameter.

Lava lamp operation depends on the steady heat output from an incandescent bulb to warm the wax and create the characteristic flow. LED or halogen equivalents do not generate the same thermal output and will not operate a lava lamp correctly. The reflector shape of this R39 bulb concentrates both light and heat upward into the base of the lamp globe. The E14 base fits the majority of UK and European lava lamp models from the 1990s onwards.

Beyond lava lamp use, the R39 reflector shape also suits small accent fixtures, display case do
